Excavator travel motor troubleshooting: what causes weak or no travel?

Expert Answer

If an excavator has weak travel, won’t move, or only moves on one side, the most common causes are low hydraulic oil, air in the system, clogged filters, low charge pressure, a weak pump, or internal leakage in the travel motor or final drive. You should also check case drain flow, hoses, and the travel brake circuit, since a brake that won’t release can mimic a motor failure. If the machine is stuck in low speed or won’t shift, the two-speed shift circuit may be at fault.
